Answer:
- 15 - 7 (Parentheses)
- 3² (Exponents)
- 8 × 2 (Multiplication)
- 40 ÷ 8 (Division)
- 5 + 9 (Addition starting from the leftmost)
- 14 + 16 (Addition after the first addition operation)
Concept:
When encountering questions that ask for simplifying expressions through operation, following the PEMDAS method would be easier:
- <u>P</u>arentheses
- <u>E</u>xponents
- <u>M</u>ultiplication
- <u>D</u>ivision
- <u>A</u>ddition
- <u>S</u>ubtraction
Therefore, the whole process of simplifying the given expression should follow the PEMDAS method. <u>For extra</u>, whenever there are two occurences of the same operation, then prioritize the leftmost and go right.
Hope this helps!! :)

Answer:
In 1979 the amount of transistors in a chip was approximately 27865.
Step-by-step explanation:
Since the number of transistors in 1974 was 5000 per chip and it increases at a rate of 41% per year, the number of transistors in a chip per year can be modelled by the following expression:
chips(t) = 5000*(1.41)^(t - 1974)
Therefore in 1979, we have:
chips(1979) = 5000*(1.41)^(1979 - 1974)
chips(1979) = 5000*(1.41)^5
chips(1979) = 27865.4183
In 1979 the amount of transistors in a chip was approximately 27865.
Answer: B) -48
Step-by-step explanation:
If the system of two linear equations 
has infinitely many solutions , then
For the given system of linear equations : 
We , will have
